Redditor Adriannezy faced a dilemma that so many of us do every Halloween: she wanted to dress up at work but didn’t want to wear a costume that would be distracting or intrusive. So she did what any self-respecting geek would do: she used technology to solve her problem.

Rather than wearing an actual costume, she slapped a QR code onto her shirt and let her co-workers point their cell phones at it all day. The code linked to this adorable picture of her in an old-school Star Trek costume. We dig the high-tech spin on the usual office Halloween costume – QR codes and Star Trek gear beat out kitty cat ears or devil horns any day.
